This is a great way to actual reveal the gender of your baby. You can buy a can of silly string from the Dollar Tree for $1. All you need to do is use double-sided tape to secure the paper of your choice around the can. The next and last step is to tie a pink or blue ribbon around the silly string and you are ready to go! Make sure not to pass these out until you are ready to actually do the reveal. Someone might accidentally spray before it is time and the secret will no longer be a secret.
